Description

Technical Field

[0001] The utility model relates to the technical field of electric shavers, in particular to a touch-type shaver. Background Art

[0002] An electric shaver is a common personal daily necessity. The traditional electric shaver mainly controls the opening and closing of the shaver by setting control buttons, which is quite inconvenient for users. Nowadays, some intelligent shavers adopt the knife net contact induction technology to control the start and stop of the shaver. Without pressing a button, the shaver starts when it touches the face and stops when it leaves the face, bringing a better user experience than button operation.

[0003] The contact induction function is generally realized by the capacitance induction of the knife net. When the shaver touches substances such as water and shaving cream, which are common in normal cleaning use, the capacitance induction device is easily affected, resulting in false touch, disconnection or even function failure, and the user experience is poor in actual use. Content of the Utility Model

[0004] In order to solve the defect that the existing contact induction shaver is easy to fail when contacting water, the utility model provides a touch-type shaver.

[0005] The technical solution adopted by the utility model is a touch-type shaver, which includes a knife net, a pressure sensor and an elastic component. The two ends of the elastic component in the elastic telescopic direction respectively abut against the knife net and the pressure sensor.

[0006] Preferably, it further includes a knife net cover. The elastic component includes a first force transmission member and a second force transmission member. One end of the first force transmission member presses the knife net against the knife net cover, and the other end of the first force transmission member presses the second force transmission member against the pressure sensor.

[0007] Preferably, the first force transmission member includes a spring pin, and the second force transmission member includes a force guiding column. An elastic section is arranged along the length direction of the force guiding column. One end of the spring pin in the direction of its elastic force presses the knife net against the knife net cover, and the other end presses against one end of the force guiding column and compresses the elastic section. The other end of the force guiding column presses against the pressure sensor.

[0008] Preferably, it includes a plurality of the pressure sensors. The first force transmission member includes a plurality of spring pins evenly distributed on the surface of the knife net, and the second force transmission member includes a plurality of force guiding columns. Each spring pin faces one force guiding column, and each force guiding column presses against one pressure sensor.

[0009] Preferably, the first force transmission member includes a plurality of spring pins evenly distributed on the surface of the cutter net, the second force transmission member includes a connecting rod and a plurality of force guiding columns, each spring pin faces one force guiding column, and the plurality of force guiding columns are fixedly connected through the connecting rod, and one of the plurality of force guiding columns abuts against the pressure sensor.

[0010] Preferably, a pair of the cutter nets are included, the first force transmission member includes four spring pins evenly distributed on the surface of the cutter net, the second force transmission member includes four force guiding columns, and every two spring pins and every two force guiding columns face one cutter net.

[0011] Preferably, the first force transmission member includes an elastic support capable of elastic deformation, and the second force transmission member includes a force guiding column; one end of the elastic support along its elastic force direction abuts the cutter net against the cutter net cover, and the other end abuts the force guiding column against the pressure sensor.

[0012] Preferably, a pair of the cutter nets are included, the second force transmission member includes a pair of force guiding columns, and the pair of force guiding columns respectively face the positions of the maximum deformation on the surface of the elastic support.

[0013] Preferably, the first force transmission member further includes a force guiding support made of a rigid material, both ends of one side surface of the force guiding support respectively abut the positions of the maximum deformation on the surface of the elastic support, and the other side surface of the force guiding support abuts the force guiding column.

[0014] Preferably, a housing is further included, and the pressure sensor and the elastic assembly are both arranged in the housing.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. When the skin contacts the cutter net and generates a force on the cutter net, the cutter net generates a displacement. Further, the cutter net drives the elastic assembly to generate a displacement. Finally, the elastic assembly squeezes the pressure sensor, and the displacement generated by the cutter net is converted into a force acting on the pressure sensor; when the cutter net is subjected to forces of different magnitudes, it will generate displacements of different degrees, so that the forces acting on the pressure sensor are also different. According to the different pressures detected by the pressure sensor, the touch-type shaver can make different touch feedbacks, such as turning on, turning off, accelerating, and decelerating, etc., realizing the contact sensing function of the touch-type shaver and simplifying the operation of the user.

[0017] 2. The cutter net is a component for contacting the skin and shaving, and substances such as water and shaving cream during shaving mainly contact the cutter net; the pressure sensor is the main electronic component for realizing touch feedback. The pressure sensor is in abutting connection with the cutter net through the elastic assembly, and it is arranged away from the cutter net and is not easy to contact substances such as water and shaving cream, thereby reducing the probability of damage to the pressure sensor, ensuring the effectiveness of the contact sensing function of the touch-type shaver, and improving the user experience.

[0033] To make the objectives, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar components or components with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0034] In one embodiment, asFigure 1-2 As shown, a touch - type razor includes a cutter net 10, a pressure sensor 40, and an elastic component. The two ends of the elastic component in the direction of its elastic expansion and contraction respectively abut against the cutter net 10 and the pressure sensor 40. The cutter net 10 can be set to adapt to the shape of the skin. The elastic component can undergo elastic deformation. Its two ends respectively abut against the cutter net 10 and the pressure sensor 40, and through pre - pressing the elastic component, the two ends of the elastic component are respectively tightened against the cutter net 10 and the pressure sensor 40.

[0035] When using the razor, the skin contacts the cutter net 10, generating a force on the cutter net 10. The cutter net 10 generates displacement, and then the cutter net 10 drives the elastic component to generate displacement. Finally, the elastic component presses the pressure sensor 40, and the displacement generated by the cutter net 10 is converted into a force acting on the pressure sensor 40. When the cutter net 10 is subjected to forces of different magnitudes, it will generate displacements of different degrees, so the forces acting on the pressure sensor 40 are also different. According to the different pressures detected by the pressure sensor 40, the touch - type razor can make different touch feedbacks, such as turning on, turning off, accelerating, and decelerating, etc., realizing the contact - sensing function of the touch - type razor and simplifying the operation of the user.

[0036] Among them, the cutter net 10 is a component for contacting the skin and shaving. Substances such as water and shaving cream during shaving mainly contact the cutter net 10. The pressure sensor 40 is the main electronic component for realizing touch feedback. The pressure sensor 40 abuts against the cutter net 10 through the elastic component, and it is arranged away from the cutter net 10, not easily contacting substances such as water and shaving cream, thereby reducing the probability of damage to the pressure sensor 40, ensuring the effectiveness of the contact - sensing function of the touch - type razor, and improving the user experience.

[0037] In one embodiment, the touch - type razor further includes a cutter - net cover 11 and a housing 50. The cutter - net cover 11 and the housing 50 are assembled together by means of snap - fit connection, threaded connection, etc. The cutter - net cover 11 and the housing 50 enclose a receiving cavity, and the cutter net 10, the elastic component, and the pressure sensor 40 are all arranged in the receiving cavity, thereby protecting the internal elastic component and pressure sensor 40, improving the waterproofness of the pressure sensor 40, and reducing the possibility of damage to the elastic component and pressure sensor 40 under the pollution of external dirt.

[0038] The two ends of the cutter net 10 are respectively a first end and a second end. A step is provided along the circumferential direction of the second end. The step can be arranged in a complete circle along the circumferential direction of the cutter net 10, or several segments can be evenly arranged along the circumferential direction of the cutter net 10. Knife net covers 11 are provided with cut openings on their surfaces. The first end of the cutter net 10 extends out of the accommodation cavity from the cut opening. The step provided at the second end of the cutter net 10 abuts against the inner surface of the knife net cover 11 under the elastic force of the elastic component, so that the cutter net 10 will not completely come out of the accommodation cavity, ensuring the "floating" effect of the cutter net 10, that is, the cutter net 10 is pre-tightened by the spring pins 20, and at the same time, the cutter net 10 can also be pressed down. The pressure sensor 40 abuts against the inner surface of the housing 50 under the elastic force of the elastic component, so that the cutter net 10, the elastic component and the pressure sensor 40 can maintain the stability of their positions. At the same time, the first end of the cutter net 10 can contact the user's skin to perform shaving and cleaning for the user.

[0039] In one embodiment, the elastic component includes a first force transmission member and a second force transmission member. One end of the first force transmission member presses the cutter net 10 against the knife net cover 11, and the other end of the first force transmission member presses the second force transmission member against the pressure sensor 40. The elastic component is split into the first force transmission member and the second force transmission member. The cutter net 10, the first force transmission member, the second force transmission member and the pressure sensor 40 are connected in sequence, which is convenient for installation, disassembly and fixation. When a single component has a problem, it can be replaced separately without affecting other components, facilitating the maintenance and replacement of components and having higher flexibility.

[0040] In one embodiment, as Figure 1-2 shown, the first force transmission member includes a spring pin 20. Under an external force, the needle head of the spring pin 20 can be compressed. After the external force is withdrawn, under the action of the spring inside the spring pin 20, the needle head of the spring pin 20 can return to its original position. The second force transmission member includes a force guiding column 30. The force guiding column 30 is provided with an elastic section 31 along its length direction. Under an external force, the elastic section 31 can be compressed. After the external force is withdrawn, the elastic section 31 can be restored. The spring pin 20 is pre-pressed along the direction of its elastic force so that one of its ends presses the cutter net 10 against the knife net cover 11 to complete the assembly with the cutter net 10. The other end of the spring pin 20 transmits pressure to the force guiding column 30. The elastic section 31 on the force guiding column 30 is pre-pressed, and the other end of the force guiding column 30 presses against the pressure sensor 40 to realize the assembly of the spring pin 20, the force guiding column 30 and the pressure sensor 40.

[0041] Among them, the elastic section 31 can be a spring, an elastic rubber, etc. As Figure 4As shown, the spring pin 20 is a two-way spring pin 20, which includes a needle tube 201, a needle core 202 and two springs. A contact protrusion is circumferentially arranged in the middle of the needle core 202. Both ends of the needle tube 201 are open. The needle core 202 and the springs are arranged inside the needle tube 201. Both ends of the needle core 202 can extend out from the openings at both ends of the needle tube 201. The two ends of the spring respectively abut against the contact protrusion of the needle core 202 and the inner wall of the needle tube 201 along the direction of its elastic force. When all the deformation components in the whole structure are springs, the force acting on the cutter net 10, the displacements of the spring pin 20 and the force guiding column 30, and the force received by the pressure sensor 40 are in a linear relationship, which is convenient for accurately obtaining the force information. In other embodiments, the spring pin 20 can also be set as a one-way spring pin 20 or other structures.

[0042] In one embodiment, the touch-type shaver includes a plurality of pressure sensors 40. The first force transmission member includes a plurality of spring pins 20 evenly distributed on the surface of the cutter net 10. The second force transmission member includes a plurality of force guiding columns 30. Each spring pin 20 faces a force guiding column 30, and each force guiding column 30 abuts against a pressure sensor 40. The plurality of pressure sensors 40 can respectively detect the pressures generated at different positions of the cutter net 10, so as to accurately obtain the magnitude and position of the pressure acting on the cutter net 10, and make corresponding touch feedback, such as starting / stopping, or adjusting the gear according to the magnitude of different forces.

[0043] Specifically, the touch-type shaver includes a pair of cutter nets 10. The first force transmission member includes four spring pins 20 evenly distributed on the surface of the cutter net 10. The second force transmission member includes four force guiding columns 30. Every two spring pins 20 and every two force guiding columns 30 face one cutter net 10. The four pressure sensors 40 can respectively detect the pressures generated by the two cutter nets 10 and different positions of the same cutter net 10, so as to sense the magnitude and position of the pressure acting on the cutter net 10. In other embodiments, different numbers of spring pins 20, force guiding columns 30 and pressure sensors 40 can also be set according to the number of cutter nets 10 and the touch mode. A bracket 21 can also be set to fix the spring pins 20 in the accommodation cavity, which is convenient for assembly.

[0044] In one embodiment, the first force transmission member includes a plurality of spring pins 20 evenly distributed on the surface of the cutter net 10. The second force transmission member includes a connecting rod 32 and a plurality of force guiding columns 30. Each spring pin 20 faces a force guiding column 30. The plurality of force guiding columns 30 are fixedly connected through the connecting rod 32, and one of the plurality of force guiding columns 30 abuts against the pressure sensor 40. As Figure 3 shown, the connecting rod 32 connects and fixes the plurality of force guiding columns 30, so that the force applied to any position of the cutter net 10 can be transmitted to the pressure sensor 40 through the connecting rod 32, thereby controlling the touch-type shaver, saving the number of pressure sensors 40 and reducing the cost.

[0045] In one embodiment, as Figure 5-6As shown in the figure, the first force transmission member includes an elastic support 60 that can undergo elastic deformation, and the second force transmission member includes a force guiding column 30. One end of the elastic support 60 in the direction of its elastic force presses the cutter net 10 against the cutter net cover 11, and the other end presses the force guiding column 30 against the pressure sensor 40. Among them, after the elastic support 60 is pre-pressed, it presses against the cutter net 10 to complete the assembly of the elastic support 60 and the cutter net 10; then the spring support 21 is further pre-pressed so that one end of the spring support 21 away from the cutter net 10 presses against the force guiding column 30, thereby completing the assembly of the spring support 21 and the force guiding column 30. By replacing the spring needle 20 with the elastic support 60, the elastic deformation of the elastic support 60 is more flexible, and there is no need to set an elastic section 31 on the force guiding column 30, which is convenient for production and reduces costs.

[0046] In one embodiment, the touch-type shaver includes a pair of cutter nets 10, and the second force transmission member includes a pair of force guiding columns 30, and the pair of force guiding columns 30 are respectively opposite to the positions of the maximum deformation on the surface of the elastic support 60. Specifically, by setting the structure of the elastic support 60, under the drive of the displacement of the cutter net 10, the positions of the maximum deformation of the elastic support 60 are on both sides of it, so that the pair of force guiding columns 30 are respectively opposite to both sides of the elastic support 60, which is convenient for the pressure sensor 40 to detect the pressure information more sensitively and obtain more accurate pressure data.

[0047] In one embodiment, as Figure 7-8 shown in the figure, the first force transmission member further includes a force guiding support 61. The force guiding support 61 is made of a rigid material and is not easily deformed under an external force, but will produce a synchronous displacement as a whole. Both ends of one side surface of the force guiding support 61 press against the positions of the maximum deformation on the surface of the elastic support 60, and the other side surface of the force guiding support 61 presses against the force guiding column 30. Thus, the position of the maximum displacement of the elastic support 60 can be transferred to any surface of the force guiding support 61, and the force guiding column 30 provided at any position of the force guiding support 61 can receive the maximum deformation of the elastic support 60. The installation position of the force guiding column 30 can be flexibly set according to the internal space, which is convenient for the installation of the force guiding column 30, reduces the probability of interference between the force guiding column 30 and other components inside the touch-type shaver, improves the flexibility of the position of the force guiding column 30, and is convenient for design and production.
